The creek originates at the toe of the Van Trump Glacier and flows south.

Just west of Mildred Point, the creek drops over small Upper Comet Falls.

[3] After dropping over the falls, the creek enters a deep canyon, which extends almost all the way to its mouth.

Most of the waterfalls on the creek were not seriously altered, but the mudflows scoured out existing vegetation and took out the bridge above Comet Falls, which was not replaced.

The floods brought huge amounts of water down, large enough to take out all the dead vegetation, left by the 2001 mudflows, lining the creek in many places and replace them with gigantic boulders in some areas, especially below Upper Comet Falls.
